Guest guest Posted January 24, 2011 Report Share Posted January 24, 2011 Well I'm just very frustrated and need a shoulder to cry on ..... A letter has arrived from my Endo, requesting I drop back down to 50mcg Levothyroxine and has noted that he still feels there is no clinical relevance to me being on it at all ! New blood tests show my TSH have dropped to 0.07 with Free T4 being 18, no reference points noted however I suspect the usual of .40 to 3.5 and 9 to 25 respectively. Whilst I appreciate the concern from him that I'm almost suppressed and that is a bad thing ? Right/Wrong ? I'm not sure and totally confused. Here is the history of blood tests over the last 12 months. March (2010) - TSH - .60 - Free T4 - 9 (No Levothyroxine) June (2010) - TSH - .20 - Free T4 - 17 (50mcgs Levo) January 2011 - TSH - 0.07 - Free T4 - 18 (75mcgs Levo) The clinical basis for the initial 50mcgs are that I show classic signs of Hypo, however TSH shows Hyper, Free T4 however confirms Hypo. Latest blood test show only very slight increase in Free T4 and significant reduction in TSH. What am I missing here, I thought the TSH would only drop if Free T4 was high, mine is still just at mid point on the reference range. Am I right to suspect that I have secondary hypothyroidism due to Hypothalimus/Protuitiary gland issue ? My axis does not seem to react/reflex how I understand it should do on a healthy person. Have received list of Drs from Sheila (thanks again), I think I'm going to have to get a second opinion. All other hormone/blood tests showing normal ranges, no Cushings or s etc and normal Cortisol and Adrenal levels. What else can I check ? Thanks for reading, Yours confused ....
